MARGINS has defined four focus initiatives, each with two focus sites. The sites were selected during a number of workshops, and the selection criteria are summarized in the science plans for the respective focus initiatives, accessible from their web pages (links above). The web pages for the focus sites can be accessed either via the navigation bar above (under "Initiatives") or the links in the map below.
MARGINS is an NSF funded program
The MARGINS Office is Hosted by Columbia University
